Overweening, smothering, spoiling, overvaluing, and idolizing the child - are all forms of parental abuse.
This is because, as Horney pointed out, the child is dehumanized and instrumentalized. His parents love him not for what he really is - but for what they wish and imagine him to be: the fulfillment of their dreams and frustrated wishes. The child becomes the vessel of his parents' discontented lives, a tool, the magic brush with which they can transform their failures into successes, their humiliation into victory, their frustrations into happiness. The child is taught to ignore reality and to occupy the parental fantastic space. Such an unfortunate child feels omnipotent and omniscient, perfect and brilliant, worthy of adoration and entitled to special treatment. The faculties that are honed by constantly brushing against bruising reality - empathy, compassion, a realistic assessment of one's abilities and limitations, realistic expectations of oneself and of others, personal boundaries, team work, social skills, perseverance and goal-orientation, not to mention the ability to postpone gratification and to work hard to achieve it - are all lacking or missing altogether. The child turned adult sees no reason to invest in his skills and education, convinced that his inherent genius should suffice. He feels entitled for merely being, rather than for actually doing.
